So “authentic” there’s an abuela “in the kitchen making the tortillas”, these “friendly” Ballard and Queen Anne eateries turn out “killer mole” and other Oaxacan specialties; arty “black-and-white images of Mexico” make the “hopping” spots feel a cut above “typical” taquerias, while “reasonable prices” and “must-try” margaritas explain the “long waits” for a table; P.S. the Queen Anne Avenue location specializes in cocktails made from its mezcal namesake.
